Thanks for you reply. The following part: 647K11 looks like the right part, but there are so many variations?

I have just taken a couple of pics to show you the actual part i am referring to, and a picture of the quick fix i have

done so far.

The first two pics show the area where the clips has broken off which has made the part loose and the third pic is my botch attempt to resolve the issue, which is push the remaining plastic clip through the thread / hole and then insert a nail through the plastic clip to stop it unclipping and popping back out, spent 6k on this car, but i know if i take it to ford they will charge me an arm and leg
